GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent NO. 705,653, dated July 29,1902. Application filed February 6, 1902. Serial No. 92,836. (No model.)

To ctZZ whom it may concern:

Be it known that we, FRANK W. GERLACH States, residing at 'Kenton, inthe county of 5 Hardin and State of Ohio, have invented certain new anduseful Improvements in Gage Attachments for Sewing-Machines; and we dodeclare the following to be a full, clear, and exact description of theinvent-ion, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention relates to gage attachments for sewing-machines.

The object ofthe invention is to provide a device of this characterwhichshallbe simple of construction, durable in use,comparatively inexpensiveof production, efticient in action, and which may be attachedto the armsof sewing-machines of the various types nowin general use and which whennot in use may be swung upwardly out of the way and be held in place inclose relation to the under side of the sewing-machine arm.

With this and other objects in view the inof parts, which will behereinafter more fully described, and particularly pointed out in theappended claims.

In the accompanying drawings, Figure lis a side elevation of thesewing-machine top and the sewing-machinearmattached thereto,illustrating the applicationotmy invention, showing in fulllinestheattachment in position for use and in'dottedlines the at: tachmentsupported in position out of use. Fig. 2 is a top plan view of theattachment. Fig. 3 is a longitudinal sectional view through theattachment when in foldedposition. Fig.

which may be formed of a tonguestruck out 'fro nthe plate and projectingdownwardly. and FRANK W. MOORE, citizens of the United" 7 and S denotethe extensible parts 015 the gage,which are connected together andmounted to slide one upon the other, the connection preferably beingmade by forming one of the bars-for instance, the bar 8-with guidetongues or lugs 9, which project upwardly and over the bar 7 and permitof one having a sliding engagement with the other. These bars are lockedto each other in adjusted po sition by a set-screw 10, which worksthrough a slot 11, formedin the bar 8, and engages a screw-threadedaperture 12, formed in the bar 7. The lowerend ofthe bar is providedwith a gage-foot 13, which is adapted to guide the material to theneedle.

The bar 7 of the extensible gage is pivoted to the hinged extension'ibyapivot-bolt 14, which is arranged in a plane at right angles to that ofthe pivot 5 and permits of the gage being swung inwardly toward theoperator.

To prevent the gagefrom swinging outwardly out of parallelism with thehinged extension 4, we provide the gage with a stop 15, which is hingedextension 4, and thus prevent the outward-swinging movement of the gage.The gage is made extensible in order to adapt it to the work beingoperated upon.

In order to prevent the gage being accidentally raised from .the.bed-plate while in use, we provide a locking-plate 16, which is attachedto the inner end of the pivot-pin 5 and is provided on its upper forwardedge with an' inwardly-projecting lug 17, which engagesthe upper surfaceof the extension 4:, the plate l6 being alsoprovided at its oppositelower corner with a screw 18, which when screwed through the plate bearson the under side of theextension 4, as shown in Fig. 6 of the drawings.It will thus be seen that when the gagerises or lowers forany purposethe plate must; necessarily turn on the pivot-pin 5 and move therewith,and itawill be obvious that when the plate is lockedin any position thegage is also locked inthat The means employed for locking the plate, andtherefore the gage, consists in providing the rear edge of the platewith a segmental slot 19, through which passes a set-screw 20, which isscrewed into a threaded opening in a lug 21, projecting downwardly fromthe portion 2 of the gage. Thus it will be seen that when the gage-foot13 has been adjusted on the bed-plate at the required place and thescrew tightened against the plate 16 the parts will be locked againstany upward movement;

In operation when the parts are in the position shown in Fig. 1 shouldit be desired to discontinue the use of the gage it is grasped andswunginwardly in a direction toward the operator, turning upon the pivot4. After it has been swung inwardly in this manner to free its lower endfrom the bed-plate of the machine it is then swung upwardly on the pivot5 and then swung outwardly on the pivot l L to parallel it with the thenfolded extension 4 and to engage it with the catch 6, which holds it ina folded position. (Shown in dotted lines in Fig. 1.) It will thus beseen that by hinging the gage to the extension by the pivot 14 said gagemay be lowered into and raised from engagement with the bedplate of themachine without the necessity of adjusting the bars '7 and 8, whichwould require considerable more time than the simple swinging of thecatch into another position.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily un- Having thus describedour invention, what we claim, and desire to secure by Letters Patent, is

1. The combination with a gage, of a plate adapted to be attached to thearm of a sewingmachine, an extension hinged to said plate by atransverse pivot, a vertical pivot for hinging the upper end of saidgage to the outer end of said extension, and means for holding the gagein elevated position under the arm of the sewing-machine, said meansconsisting of a catch-hook projecting from said plate, substantially asset forth.

2. The combination with agage, of a plate adapted to be attached to thearm of a sewingmachine, an extension hinged to said plate by atransverse pivot, a vertical pivot for hinging the upper end of saidgage to the outer end of said extension, means for holding the gage inelevated position under the arm of the sewing-machine, and means forlimiting the outward movement of the gage with respect to the extension,said means consisting of a stop-lip projecting downwardly from the gageand adapted to abut against the extension, substantially as set forth.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
